OSU Network Announcements

Information Services experienced a failure in the network core during regularly scheduled maintenance this morning. We have restored some basic services at this time (9am) but are working on additional issues and still have many inter-dependent systems nonfunctional. We will notify the campus community when all services have been restored.

If you have questions or concerns about this outage, please contact Network Engineering at net (at) oregonstate.edu or call 737-HELP.

Information Services suffered a catastrophic failure of the core network this morning while conducting regular announced maintenance starting at approximately 6:45am. The root cause of this failure was identified and services restored at approximately 9:25am. We are currently working with our vendor to understand the technical problems and will be conducting an architecture review and review of procedures to understand how this happened and how to avoid it in the future.

If you have any questions or concerns please call the OSU Computer Help Desk.

On March 3 2015, between 9:00AM and 1:00PM, we will be redirecting a number of processes to point to a table which has been restructured (old table: SERSSGP, new table SYRSSGP). This change has been tested in DEVL. Updates include replacing one Banner INB form (SEAASGN will be replaced with SYASSGP) and updating various processes which currently use the old table.

The only impact visible to users will be the form change. The primary users of SEAASGN (Registrar’s office and ID Center) have been notified of the form change and have tested the new form in DEVL. The process changes will be verified, and the old table will remain in place until all dependencies are removed. If necessary, these changes can be easily reversed.

Information Services conducted emergency maintenance this morning on OSU_Secure to address a failing authentication server. Mac and PC clients may warn of a security certificate change. This is expected behavior and does not represent a security risk.

If you have questions or concerns, please contact the OSU Computer Help Desk.

Outage Window: Start: 02/11/2015 6:00 AM End: 02/11/2015 6:15 AM

Reason for outage: Preventative maintenance.

Impact:

Departments affected: All departments where the OSU_Secure wireless network is available.

Locations affected: All locations where the OSU_Secure wireless network is available.

On Wednesday 1/28, at 6AM to 7AM, we will be rebooting some core network services like DNS, http proxy, RBLs, and other ancillary/supporting servers. These are rolling updates to apply important software patches to nearly all of our Linux-based servers. Most users will be unaffected or briefly affected during the outage window. Additionally, users will not be able to use MAC-based authentication for OSU_Access briefly during this time. OSU_Secure will not be affected. Access to Maintain to make DNS or DHCP updates will also be interrupted briefly.

In the past hour, the core network has suffered from an intermittent link, causing errors and packets to be dropped. We have shut down this suspect port, and it appears all traffic has rerouted to redundant links. The core network appears stable again at this time.
